Diff Bulkheads.

Front & rear bulkheads feature a semi-split design for easy diff access while adding the valuable diff height adjustment. The bulkhead design also uses a bushing for the gearbox input to alter the alignment and height of the bevel drive gear with the diff height. In addition to matching the diff height adjustments, this input bushing also allows the front central driveshaft to operate with a reduced angle for less friction and wear on the CV joint components and improved driveline efficiency.

The XB8 bulkheads allow fast and easy differential access for setup changes or servicing by removing only 4 screws from the upper gear box cover while the lower section remains mounted to the chassis with the lower arms and suspension holders installed. This super-fast diff access is featured on both front and rear gearboxes.

Chassis Braces.

The mounting of the chassis brace to the bulkhead eliminates transfer of energy from the suspension via shock towers to ensure more precise landings and more off-power traction.

The included rear brace is moulded from a medium-stiff composite mixture for improved flex & rigidity, and allows the mounting of optional graphite inserts to reinforce the chassis brace to make it even stiffer for particular track conditions.

Side Guards.

Side guards feature a larger bottom radius to give better stability on rough tracks. The radius of the side guards increases the car’s longitudinal flex. The side guards are moulded from a special composite mixture for increased flex that helps generate more traction.

The tough composite side guards protect the car, muffler, and fuel tank from side impacts. The side guards perfectly fit the chassis and seal against dirt.

Optional side guard braces allow for very efficient and easy chassis flex adjustment to adjust the handling of the car to different track conditions. By adding the graphite braces, the entire chassis is reinforced and stiffer flex will improve handling in high-traction conditions. 

Chassis.

The chassis features chamfered front edges which prevents dirt pick-up when the chassis contacts the track. The chamfered edges will not “cut” the dirt, but rather the dirt will slide along the chamfered edges and not get stuck at the front of the chassis.

The side guards were moved 4mm rearwards to ensure that under full throttle and full steering lock the inflated tires will not contact the side guards and can operate freely.

Drivetrain.

The XB8 is a conventional shaft-driven 4WD off-road car featuring:

• Front & rear gear differentials with adjustable oil viscosity, featuring 46T crown gears and 13T pinion gears

• Central differential with adjustable oil viscosity, featuring 48T spur gear with standard 14T engine clutchbell

• Front & rear universal drive shafts, and central CVD drive shafts

Steering Block.

Steering blocks from a harder composite material provide a more responsive feel especially on bumpy tracks and retain free suspension movement in dusty conditions for better consistency. The steering blocks are super lightweight yet extremely strong, featuring a larger outside 8x16x5mm ball-bearings for increased reliability and lifespan.

The uprights are super-strong and feature a larger outside 8x16x5mm ball-bearing for increased reliability and lifespan.

Brakes Linkage.

Brake linkage assemblies with stiff springs and ball-shaped bushings result in a more reliable and consistent brake operation through even the longest runs.

Wickerbill Wing.

Wickerbill rear wing features more downforce that helps increase traction when needed, and has 12 pre-marked air flow hole positions that can be opened to fine tune downforce for any conditions. The wickerbill plate is mounted via 5 screws for easy downforce setup.

Made from a strong special composite mixture, the wing was designed to survive severe abusive and extreme crashes while keeping its shape. 

The optional Lexan wing has an adjustable position and consists of two pieces: the main wing and the center fin that adds more stability and increases strength of the wing around the mounting area. The rear section of the wing is pre-bent to reinforce the wing and eliminates the use of additional heavy composite wickers. This makes the back of the wing strong while still allowing for wing flex in a crash. The pre-bent rear section of the wing is an important detail to create the desired downforce. Used by the factory team and suggested for all track conditions.

The design of the body improves the handling for all skill levels, from local racers to World Champions. The “Eazy” Body makes the XB8 more stable at speed and more reactive in the corners.

The redesigned sides of the body improve stability at higher speeds. The round front cab and profile make the XB8 easier to drive. Some of the redesigned down force areas increase the speed of the car. The central fin on the roof help control the car more precisely making handling more predictable. Overall, the “Eazy” body is the most significantly improved performance off-road body we have designed.

The front cabin was redesigned with a wider and cab forward design so both left and right sides generate matching downforce even with the cut-out opening for fuel tank.

The body is fully compatible with the XB8 and XB8E platforms.

Anti-Roll Bars.

To increase overall traction in all track conditions, the front anti-roll bars were changed to 2.2mm and the rears to 2.4mm.

Anti-roll bars, manufactured from spring steel material, are easily mounted to front & rear diff cases with easy adjustment using the adjustable linkages.

Anti-roll bar wires of different thicknesses are optionally available for fine-tuning.

Turnbuckles.

To guarantee maximum reliability, all turnbuckles are manufactured from a special blend of HUDY Spring Steel™ which is specifically formulated for turnbuckles. The turnbuckles have a tougher core, making them very well suited for the steering system and rear upright linkages. 

Ackermann.

The specially-designed ball studs eliminate steering lock and allow greater steering radius. The integrated backstops ensure that the pivot balls do not disconnect in crashes.

Ackermann is easily adjusted on the machined Swiss 7075 T6 steering plate to ensure highest reliability and strength.

Pivot Balls.

To increase the reliability and free movement of suspension even in the extremely dusty conditions, the pivot ball cups are moulded from a special graphite material that ensures more free movement even when dust builds up.

To reduce weight and lower the CG, the front upper pivot balls are combined with a steel threaded part for maximum strength. The aluminum ball is machined from premium Swiss 7075 T6 and additionally hard coated for extended lifespan.

Alu Wheel Hubs.

To accommodate the geometry, the XB8 includes rear wheel hubs with a +2mm off-set while the front features the +1mm off-set wheel hubs.

Ultra-lightweight 17mm wheel hex drive hubs are CNC-machined from Swiss 7075 T6 black-coated aluminum.

The alu hex hubs are specially machined to reduce rotating weight while guaranteeing wobble-free wheel mounting. 

Central Diff Gear.

The central differential is an extra-large size for increased reliability and performance. The differential is over 5mm larger, with an increased oil capacity to reduce oil overheating in long runs, helping to keep differential performance as consistent as possible. 

Internal Diff Gears.

The 20T and 10T internal diff gears are larger to ensure reliability and reduce diff oil overheating. The greater number of teeth ensures more precise fitment and engagement.

Pressed-steel differential bevel and satellite gears are heat-treated and machined for superior precision and smooth operation. 

Diff Outdrives.

Updated diff outdrives accommodate the stronger diff pins. 

To reduce rotating weight, the super-lightweight diff outdrives are machined from HUDY Spring Steel™ which allows unnecessary material to be removed to further reduce weight without affecting durability. The inner portions of the outdrives are additionally hand-ground for maximum precision and fitment into the diff case.

All outdrives are hardened using HUDY’s own special hardening process for extended lifespan and reliability.

Gear Differentials.

Both front and rear differentials are identical for easier maintenance and servicing.

The Large Volume diffs feature higher capacity cases, stronger diff pins, and large internal gears with more teeth for improved differential action, consistency and overall reliability. The larger volume of the differential and the shape of the gear teeth help reduce oil overheating.

Center Differential Access.

Access to the center differential is super easy by releasing the upper deck with only 4 screws. The low center diff housing is sized to accommodate optional spur gears, and the stands are lowered to keep the weight as low as possible and to allow smaller central diff gears to be used. The center diff housing stands hold the effective and race-proven brake system.

Wing Holder Brace.

To help prevent rear gear box breakage during crash impacts, the rear wing construction features wing holder brace that transfers crash impact energy from the wing and shock tower to the chassis where it is centrally resolved.

The wing holder brace includes an integrated body post as well.

Radio Box.

The XB8 includes the Hard composite radio box that is more rigid in higher temperatures to improve the precision of servo movement and has more room for the receiver battery pack.

The optional Soft composite radio box increase chassis flex. This can help improve handling characteristics in some low- to medium-traction conditions.

The 1-piece electronics assembly is very compact and can be quickly & easily removed for servicing and cleaning. It requires removing only a few screws from the bottom of the chassis to remove the entire electronics assembly from the car.

The large, molded radio box features a very clean design and layout that places the weight in key areas for proper balance. The batteries are placed along the front centerline of the chassis, and the lightweight receiver is placed on its side at the rear. The easy-access radio box is mounted on the side of the car and is secured by the fewest possible screws.

Fuel Tank.

The XB8 fuel tank complies with the latest rules featuring the transient jet that ensures the internal volume of the fuel tank cannot be changed by pulling the fuel line.

The extra-strong fuel tank features an integrated floating stone filter that ensures that the fuel pickup will always be in the correct orientation, even if your car isn’t. This fuel pickup system will allow fuel to continue to flow to your engine, even while waiting for a marshal to reach your inverted car and put it back on its wheels.

Internal baffles inside the fuel tank ensure that the fuel will always be in the area around the fuel line intake so even during large jumps the fuel will be constantly supplied to the engine.

The fuel tank cap features a very strong spring which ensures the cap will always close after refueling, and the specially designed rubber gasket perfectly seals the fuel tank and ensures no fuel will leak outside.

Engine Mounts.

The engine mounts extend up to the engine front bearing for improved chassis reinforcement in the longitudinal direction, and in jumps this will minimize chassis bending between the clutchbell and spur gear.

The CNC-machined aluminum engine mounts are made from superior-grade, lightweight alloy which helps to dissipate engine heat. The engine mounts are easily adjustable to obtain proper gear mesh.

High-Torque Clutch.

The high-torque clutch features a lightweight flywheel. The flywheel features reduced mass for quicker engine response and clutch engagement.

The high-torque clutch provides smooth, continuous power transfer from the engine to the driveline. With the included Hard springs, the clutch engages higher in the RPM range, resulting in more controllable power during acceleration while still maintaining good engine response and performance on jumps.

The Swiss 7075 T6 clutch shoes are small, lightweight, and designed for engagement during the entire travel of the shoe. The shoes are less sensitive to wear and results in improved lifespan.

The smaller diameter allows the flywheel to be more protected after landing large jumps, so there is a reduced chance of accidental engine stoppages.

The extra-tough flywheel nut is machined from Hudy Spring Steel™.

The clutch is equipped with hard clutch springs; optional soft and medium springs are also available.

4-Shoe Clutch.

The optional 4-shoe clutch features smaller, lighter internal parts, and the design allows for more balanced clutch bell engagement compared to a traditional 3-shoe design.

The 4-shoe design allows the use of multiple combinations of different shoe hardness and spring tensions for clutch engagement tuning, and even allows for mixed combinations of shoes and springs which gives ultra-fine engagement choices. There are 4 different hardness of shoes and 3 different hardness of springs available. Changing the clutch configuration is very easy thanks to the special assembly screws that hold the shoe and spring.

SOFT clutch setting generates the highest amount of traction and engages earliest;

MEDIUM clutch setting allows more clutch slippage and engages later;

HARD clutch setting engages latest and provides more revs to engine.

Shock Pistons.

Ultra-precise shock pistons feature 6-, 8- and 10-hole options. The big-bore pistons are molded from tough, well-proven Delrin® material to provide smooth action and durability. The precision molding production process ensures perfect piston roundness after production, so that the pistons move super-smoothly inside the shock bodies for identical perfect action in all four shocks.

Shock Springs.

The XB8 includes the 4-dot front shock springs for stability. XRAY shock springs are manually measured, selected and matched into pairs to guarantee precisely equal length and damping characteristics.

Silicone Oils.

HUDY Exclusive Silicone Oils are manufactured in Europe and each batch is laboratory tested and calibrated to ensure the highest possible consistency and quality from batch to batch. Based on the industry-standard cSt rating, the new line of oils will be easy to identify, adjust, and feel.

Socket Head Cup Screws.

To increase lifespan and improve ease of servicing, socket-head cup screws are used instead of regular hex screws. The socket-head cup screws are stronger and more reliable, making it easier to work on the car.

Ball-Bearings.

A full set of 24 high-speed ball-bearings are used throughout the XB8 drivetrain.

All-new grease lubricated bearings are included for the pinion gears and diffs to increase reliability and lifespan, especially in dusty conditions. The remaining bearings are degreased and oiled with AeroShell® Fluid 12 to reduce drag and maximize driveline efficiency.

Graphite Grease.

The XB8 includes premium HUDY Graphite Grease - a high-performance, advanced-technology semi-fluid lubricant which incorporates both extreme pressure additives and finely-dispersed graphite for load carrying. HUDY Graphite Grease is intended primarily for the lubrication of rotating parts and loaded gears. In addition to providing outstanding load carrying, it is formulated to have excellent adhesion and resistance from "flinging off" under extreme conditions. HUDY Graphite Grease reduces wear and increases parts life.

Air Filter.

To minimize the dust getting into the air filter, the air filter cover mounting positions were modified and improved.

The smooth-flowing, efficient air filter is made from two parts. Air filter oil is included as standard. The universal rubber elbow allows fitment to most standard 1/8 buggy engines.

2-in-1.

The XB8 design allows to accommodate either the C-hub or Pivot Ball suspension. The included Pivot Ball suspension can be easily exchanged for the optional C-hub suspension to accommodate to the particular track conditions.

C-hub Suspension.

#350910 XB8/XB8E FRONT C-HUB SUSPENSION - SET

The optional C-hub is perfectly suited for smooth and short technical tracks & smooth surface conditions. At these track conditions the C-hub suspension generates increased frontward traction as well increased overall traction with enhanced steering.
